jgroups-all.jar (required ): JGroups functionality, including demo and junit apps. If a smaller JAR is required, this can be done by downloading the source distribution and invoking the "jar" target, which creates a jgroups-core.jar file (ca 1MB).
2, To test whether JGroups works okay on your machine, run the following command twice.If you started them simultaneously, they could initially show a membership of 1 in their title bars. After some time, both windows should show 2. This means that the two instances found each other and formed a group.When drawing in one window, the second instance should also be updated.
